Purpose


GQPPLR	(wtype, pli, errind, lntype, lwidth, coli)

APL code	1400
GKS RCP code	X'3800C700' (939575040)

Function: To inquire predefined polyline representation.

Inquiry function. Returns the representation associated with a predefined polyline index for a given workstation type, from the workstation description table.

Parameters

The workstation type.

pli (specified by user) (fullword integer)
The predefined polyline index (1 ... n).

errind (returned by GDDM) (fullword integer)
The error indicator.

lntype (returned by GDDM) (fullword integer)
The line type. The possible values are:

0 (GLSOLI): Solid line
